植物修复农田土壤重金属污染需要经历一个长期的过程,而大部分用来修复的植物都不具备利用价值,不能给当地农民带来经济收入。因此,一些农作物由于其较大的生物量和一定的经济价值,在植物修复土壤重金属污染的应用中受到广泛关注。是在重金属(Cu、Zn、Pb、Cd、As、Hg)复合污染的郴州矿区废弃农田种植油菜、玉米和油葵,研究油菜-玉米和油-油葵两种种植模式对土壤重金属污染的修复潜力。实验结果表明:三种作物在复合污染土壤中对重金属都表现出一定的耐性及吸收积累能力。向日葵的根和叶中重金属Cd、Cu的含量都很高,其中Cd在向日葵的各个部位的富集系数(BCF)及Cu在向日葵的根和叶的富集系数(BCF)都...

Plants needs cost many years to remediateheavy metal-contaminated croplands, and because some plants lack economic value, farmers often have no income during this period.Therefore, selecting suitable plants tolerant to heavy metals and producing products ofeconomicvalue may be a key factor in promoting the practical application of phytoremediation polluted soils. Many studies have demonstrated that some cash crops, which have the ability to attain large biomasses and accumulate metals, are highly tolerant to metal pollution.In order to fully ut...
